ABMORED TIRE.

Speciflcatio of Letters Patent.

Patented Apr. 2, 1912.

To all 'whom it may concm Be it known that I, VICTOR A. ROUILLIARD, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented an Improved Armored Tire, of which the following is a s ecification.

The object oi my invention is to provide an improved armpr or proteotor for rubber, especially pneumatic, tires of automobiles, motorcycles, and other -motor-propelled vehicles, whereby the will be made practically puncture-proo and without materially increasing their thickness and weight and with but little addition to their cost. To this end, I apply a metallic coat to the outer surface of the superposed layers of the tire, the operation beingefected by electro-deposition in the process of manufacture of the tire.

The details of the invention are hereinafter described with reference to the accompanying drawing, in which- Figure '1 is a sectional perspective view of a portion of a neumatic tire .constructed in accordance wit my invention. Fig.i2 is a longitudinal section of a portion of the tire. The tire illustrated in` the drawing is formed of an inner cylindrical rubber ortion 1 having a suitable base by which t is Secured 'to the rim of a wheel. `U on the outer side of the part 1 is a series o superosed rubber layers indicated, respeotively, y numerals 2, 3, 4, 5.

The inner cylinder or body portion 1 may be molded from rubber or from a rubber I apply a coat in the same manner to the surfaceor oter side of each of the several layers 2, 3, 4. The coat. being quite thin has great elasticity and will confor'm to the undulationsof the several parts on which it is applied, which -may be due to suddenor p'olonged compression either locally or geri erally on the outer side of the tire. Thus, while adding but little to the weight ad cost of the tire as a whole, it renders it practically invulnerable to puncture; thus adding very greatly to the dur'ability of the tire.

What I claim is 1. A rubber tire comprisin V layers and a protectng metallc coat electrodeposited on one of them, substantially as described.

one or' more 2. A pneumatic rubber tire composed'as v 4 to its exterior, peripheral portion of a series of superposed layers each having a protecting metallic coat formed by electro-depostion, substantially as described.
